Generally yes in any tier with a big enough pool, and has been my experience. I've been playing team based competitive shooters for over 2 decades, and while I occasionally notice an obvious cheater with amazing aim and improbable aim jumps during replays. My experience is that they often aren't very good at the game in general. Or at least, it's their crutch to play at my level. Cheating was a much bigger problem for me when I'd personally pick the servers I played on, but I hardly think about it any more. Modern match making tends to be pretty good at leveling the playing field. Cheating kind of sucks, but generally I don't notice on the games I like to play. Plus, there's just as much chance the cheater will be on my team as the opponent, so it evens out that way as well.
